Torque compensation for bow

Abstract

Bow with a string sight and a sight mounted on the middle piece of the bow, characterized in that immediately before or during the aiming process with the string sight and the sight mounted on the middle piece, the image of the string appearing in a mirror permanently mounted on the middle piece of the bow or of a device attached to the string is brought into alignment with a mark applied to the mirror by changing the vertical torque on the handle of the middle piece.

Description

Technical field

[0001] The invention relates to the aiming devices of sports bows. State of the art

[0002] A variable torque at the riser of a bow, especially a compound bow, can lead to significant lateral deflections of the drawn bowstring relative to the riser, thereby affecting accuracy.

[0003] The effects of variable torque on aiming accuracy are usually minimized by maintaining a constant hand position, but this cannot be quantitatively controlled. Object of the invention

[0004] The invention is based on the objective of using an additional device to keep the resulting torque at the handle and around a vertical axis constant or to minimize its deviations from a target value. Technical solution

[0005] This problem is solved with the features listed in claim 1 by firmly connecting an additional mirror to the bow's central part and aiming it with a defined eye position, and by bringing the mirror image of the bowstring appearing during or immediately before the aiming process into alignment with a mark on the additional mirror, if necessary, by changing the hand position.

[0006] Several versions of this torque compensation are possible. The additional mirror can appear within the field of view of a peep sight (e.g., a "peep sight") or outside of it during the aiming process.

[0007] Alternatively, deviations of the torque from a target value can be detected by aiming the additional mirror with the chord sight immediately before the actual aiming process.

[0008] The setup can also be used with a mirror sight.

Claims

[1] Bow with string sight and sight mounted on the middle part of the bow, characterized by , that immediately before or during the aiming process with string sight and sight mounted on the centerpiece, the image of the string or a device attached to the string appearing in a mirror fixed to the centerpiece of the bow is brought into alignment with a mark on the mirror by changing the vertical torque on the handle of the centerpiece. [2] Arrangement according to claim 1, characterized by , that the mirror appears in the field of view of the chord sight during the aiming process with a string sight and a sight mounted on the center piece. [3] Arrangement according to claim 1, characterized by , that the mirror appears outside the field of view of the chord sight during the aiming process with a string sight and a sight mounted on the center piece. [4] Arrangement according to one of the preceding claims, characterized bythat the mirror has a circular, ring-shaped or other part of a symmetrical shape outline or a suitable additional marking on the mirror surface so that the mirror or the additional marking on the mirror can be centered in the field of view of the tendon sight or held in a defined position. [5] Arrangement according to claim 1, characterized by , that instead of a string sight a mirror sight is used, whereby the image of the eye's pupil is aligned with an additional mark on a mirror fixed to the center section of the bow. [6] Arrangement according to any of the preceding claims, characterized by that the mirrors used have a nominally non-planar or a concave shaped surface.
